CLOSURE Application filed October 13, 19265. Serial Ho. 141,842.

This invention relates to improvements in closures end more of the type provi ed with air chambers which are vented to the outside atmosphere and to the inside of the devices being closed.

laleretoiore, in closures of this type, the air chenobers thereof have been vented to the outside atmosphere by apertures in the outer walls of the closures, which not only mar the appearance of the closures but also leave seid apertures unprotected so that they often become fully or partially closed by dirt and the like. The object of the present invention is to provide an improved closure having a novel arrangement of vent means for the air chamber thereof, so that while said chamber is vented to the outside atmosphere and to the inside of the device being closed, just as in prior closures of this type, the outer wall of the closure is free of perforations Further ohjects of the invention are in port obvious and in port will appear more in deteilhereinefter.

in the drawings, which represent one suitable embodiment of the invention, Fig. 1 is a vertical sectional view oi my improved.

closure applied to the tubular neck ortion of a "tank or the like; Fig. is o ottom plan viewoi the closure; Fig. 3 IS a top v len view of the closure" Fin, 4 is a to plan view of a? Fig. 1; and Fig. 5. is a view sizni or to Fig. 1 but taken degrees thereto In Figs. 1 e or" the drawings, the closure is shown pied to the cylindrical neck or filler portion Ii oien automobile fuel or other tank 2, said neck portion being either an integral part of said tank or separate therefrom, as shown, provided with a,

lateral base flange 8 for secnrement to said' tank.

Enid neck portion is provided its upper end with an inwardly extending, substantially horizontal. flange 4 which terminates in a depending flange 5. two diametrisally opposite points, flanges l 5 are cut away, es indicated in Fig. i, to provide two openin s or passageways 6, through which the loo ing fingers of the closure ere ode ted to be passed, as will later eppeer; .1. e cutting away of portions dongs dend' 5 a, W. F m 1 v two depend i merge ns 5 articula-rly, in closures 'culer disk 13, the outer edge of which tubuler neciz portion of.

tions with recesses 1 a, shown), upon which dwell portions e locking fingers of the closure ere 1 to rest when the closure is-in fully sect position upon the tank neck portion.

(Joining now to the closure forming c subject matter of the present invention, closure includes an outer end an inner well separated to provide on eir chamber therebetween. The outer wall includes at substantially circuler, dcmesheped top 13 tion ll. end a depending or portion 12 which is slightly lsrger in ameter than the tank neck portion 1. iinner wall includes e substentielly ilet, c

crimped or otherwise snitehly secured to outer wall at the junction the skirt portions thereof, is .vided with a centre-lily on extending annular portion 14 terminetin in a circular ofiset porti n 15, said 14, 15 forming a downwardly opening cess '16 Within this recess end engaging the offset portion 15 is the suhetontially body portion 17 of e. locking-or secu member, the two opp l curved edge ticns 18 of said body A .tion being crimp or otherwise suitably to the upwerw 1y extending disk The portion of said mom? s prov-id at each of its two opposed straight portions 19 with an inherently resilient locking'or securing finger portion 20 extending downwardly end outwardly from body portion, as clearly indicated in Fig. 5.

The closure is applied to the tank neck portion 1 in the usual manner of bayonet joint connections, looking or lingers 2,0 oi the closure being passed down through the peeeigeweps or i til) tion. The closure is then turned in a clockwise direction which causes the locking fingers thereol to ride up the cams 7 with yielding efi'ect, the rotary movement of the closure being continued until said fingers strike the stop portions 8. To remove the closure, it is only necessary to turn it in the reverse direction, as will be readily understood.-

Coming now to the vent means for the air chamber 10 of the closure, said air chamber is vented to the inside oi the neck portion 1 (and hence to the tank 2) by one or more apertures in the central zoneot the inner wall 13, and which may be located in one or both of those parts of the disk offset portion not covered by the body portion 17 of the closure locking member. In the embodiment here shown, said disk ofilset portion is provided with two apertures 23, each of which is arranged above one of the downwardly and'outwardly extending closure locking lingers 20, so that said apertures are bullied by said fingers.

The means for venting said air chamber 10 to the outside atmosphere comprises one or more apertures or openings in or near the outer edge portion of" the closure disk 13. In the present embodiment, two such openings 24.- are shown, which are formed by suitabl notching the outer edge portion of said disk, as clearly indicated in Figs. 1 and '2. llnasmuch as the skirt portion 12 of the closure outer wall is slightly larger in diameter than the tank neck portion 1, an annular channel or space is provided between said portions. This space is, of course, in direct communication with the outside atmosphere and ,in communication with the air chamber 10 by means of the disk notches 2 I lit will thus be seen that the air chamber 10 is efiectively vented to both the inside of the device to be closed and to the outside atmosphere, and at the same time, the outer wall of the closure is free of disfiguring apertures. Moreover, the apertures 24, are protected by the outer wall of the closure and are therefore not likely to become closed by dirt or the like. They also serve admirably as drain vents or outlets for paint, enamel, lacquer or any-other coating material applied to the cap as a rotective coating'or for ornamentation. Any such material which may find its way into the chamber 10, as by immersion of the cap in a bath of the coating material, readily drains away and neither becomes trapped in said chamber or tends to clog the several vent openings, particularly because vents 2d are fairly close to the narrowing outer periphery oi the chamber 10 where its wall surfaces converge, and toward which any liquid drains.

Pref-rably, the closure provide neeaoec an annular gasket 28, of cork, leather or the like, and slightly smaller than the disk 13 so that the vent notches 2a in the outer edge portion of said disk are not covered by said gasket. When the closure is applied to the tank neck portion, as shown in Figs. 1 and 5, said gasket liesbetween an annular sealing seat which surrounds the recess in the'central zone of the closure disk 18 and the inwardly extending, horizontal flange of the tank neck portion. When the closure is removed from said tank neck portion, the gasket is prevented from becoming disassociated from the closure by the outwardly extending closure locking lingers 20, al though other and additional means may be provided, if'desired.

What l claim is:

1. A closure for receptacle prising inner and outer walls tions separated to provide an air chamber therebetween, securing means with the inner wall, vent means in said inner wall providing communication, when the closure is applied to the neck, between said air chamber and the outside atmosphere, and other vent means in saidinner wall providing communication between said air chamber and theinside oil the neck, when the closure is applied to the neck, said securing means being so arranged as to pro= vide a bafie for one of the vent means oi the inner wall, 2. closure for receptacle necks, compris= mg mner and outer walls havin portions separated to provide an air chem or there between, securing means associated with the inner wall, vent means in said inner wall providipg communication, when the closure is appli to the neck, between said air charm her and the outside atmosphere, and other vent means in said inner wall providing communication between said air chamber and the inside of the neck when the closureis applied to the neck, said securing means he ing so arranged as to provide a bat le for the second named vent means.
